Techniques for vetting inbound calls in a telecommunication network

At least one non-transitory machine-readable medium comprising a set of instructions executable on at least one computing device, the set of instructions to:

• receive a SIP INVITE from a destination carrier servicing an inbound customer intended for a destination user agent (UA) device of the inbound customer, the SIP INVITE including a current origination identifier (ORIG ID) comprised of a fixed length character string generated from a hashing algorithm based on a specified set of inputs that include a customer identifier, an Internet Protocol (IP) address indicative of the point of ingress into the originating carrier's network, and an ID indicative of the UA device that initiated the SIP INVITE;
• access a database of stored ORIG ID character strings, each stored ORIG ID character string in the database having been included with a previous SIP INVITE that has been associated with an unwanted inbound call;
• analyze the current ORIG ID character string to determine if it matches any stored ORIG ID character strings in the database;
• when there is a match to a stored ORIG ID character string, not forward the SIP INVITE to the destination UA device;
• and
• when there is not a match to a stored ORIG ID character string, forward the SIP INVITE to the destination UA device.

A computer, comprising:

• one or more processors;
• and
• a non-transitory computer readable medium to store a set of instructions executable by the one or more processors, the set of instructions to cause the one or more processors to:
• receive a SIP INVITE from a destination carrier servicing an inbound customer intended for a destination user agent (UA) device of the inbound customer, the SIP INVITE including a current origination identifier (ORIG ID) comprised of a fixed length character string generated from a hashing algorithm based on a specified set of inputs that include a customer identifier, an Internet Protocol (IP) address indicative of the point of ingress into the originating carrier's network, and an ID indicative of the UA device that initiated the SIP INVITE;
• access a database of stored ORIG ID character strings, each stored ORIG ID character string in the database having been included with a previous SIP INVITE that has been associated with an unwanted inbound call;
• analyze the current ORIG ID character string to determine if it matches any stored ORIG ID character strings in the database;
• when there is a match to a stored ORIG ID character string, not forward the SIP INVITE to the destination UA device;
• and
• when there is not a match to a stored ORIG ID character string, forward the SIP INVITE to the destination UA device.
